Hi @guidorugo,

Thanks for reporting!

I believe the issue is with the python version used. Blast Radius requires v3.5 or later, however the docs aren’t explicit about this, and the setup script doesn’t check.

An easy alternative is to use the docker image, as described in the readme.

Holding this issue open, because the docs really ought to mention this...

Got the same error on CentOS 7.4 with Python 3.6. Changed #!/usr/bin/python3.4 to use 3.6, but no juice.

Hey @sbkg0002

I'm planning some long overdue fix-ups in this area, for the weekend. Recommend using the Docker image as an interim solution, since it hides all of the nastiness of Python versioning.

[sbkg0002]

Thanks for the feedback and work. Still have the workspace impedement for now, so I'll have to wait.
